CW: Codegen issues with the new Constant

We need to renumber Constants to have stable form signatures (https://github.com/firedrakeproject/firedrake/issues/2999).

More generally I also want to know the exact abstraction provided by a Constant. When do we expect users to use them? Should it be possible to differentiate w.r.t. them? If we had vector-valued R Functions would they ever be required? (I think yes since sometimes identifying the right domain is hard).
